What is the proper way to drive an LED on an embedded system?
20mA is at the upper range of what I would consider driving with an MCU. Be sure to check the spec, and determine whether the MCU is better at sinking or sourcing current, as this would dictate which way around the LED goes, and whether the other end is connected to through a resistor to ground or V. Also consider what the total power sunk or sourced by the MCU would be - does it exceed the rating for the MCU? How about the thermal performance?You may find that it is much better to get a high brightness LED with a 20mA spec and drive it at a lower current to achieve an appropriate level of brightness (eg. for display or indication)For higher current applications, such as 3W LEDs where voltages and current greatly exceed what the MCU handles, you should use a constant current driver - many are available (eg. LM3414, CAT4104), and can be simple or complex, depending mostly on how consistent the forward voltage of the LED is from one LED to the next (usually not very consistent) and whether you plan on implementing only one LED, or if you're going to take it to production and can't possibly tweak every circuit that rolls off the line, total string voltage, and a number of other possible factors. If it's a one-off with very consistent source voltage, then you can just put a resistor and MOSFET in series and use the MCU to drive the MOSFET, but this provides poor sensitivity to changes in supply voltage, and poor brightness matching between LEDs that might be side-by-side.

------What is MGTOW and/or the red pill?
Two different things , red pill is a mindset that men embrace where you are to be the best you can be for yourself .Like everything it has it's extremes where men will go into the whole alpha /beta thing and preach it to everyone and call others on it ,defeating the purpose .In the most important meaning of it , it's being aware of what it means to truely be manly (physically,mentally ,financially, self confident , courage and a controlled level headed ego ).
MGTOW men going their own way. This in itself has a vast vast spectrum and is often mixed up with red pill .The spectrum spans from men who genuinely hate woman because they have never been successful with them so they go solo (often not by choice).Then there are the men who have been destroyed by a woman either divorce ,financially , cheated on and so on and so forth.
.In final there are just those men who chose to pursue their careers and financial freedom and refuse to get married or attached beyond dating periodically .Sadly I've seen too much of this on the bad side of the spectrum where men blame woman for exploring through hypergamy , manipulation and incapable of loving like a man.I believe this simply men not understanding themselves and even less woman ,looking for a source to their misery and playing the victim.
. It will simply accomplish a life of bitterness and loneliness, resulting in a waste of what's most precious to all human beings ,(TIME)
------What are your most memorable cooking fails that led you to throw the food away?
This reminds me of the time when I tried to replicate my mothers Kofta dish.To say, It was a fail would be an understatement.I usually cook good food and so I was confident. While growing up, Kofta was one of my favorite dishes and I had not have it in a really long time so I was badly craving for it.I started with making Kofta first and to add a twist I used corn flour for the coating.Kofta is a type of Indian fritter made with gram flour and grated bottle guards. Traditionally Kofta is not made with corn flour coating ( for those who are not familiar with the dish)When I tried to fry them in pan, it tore open and everything became a mess!My pan, now had some gram flour paste swimming in the oil openly. I continued even after this major crisis and tried to fry another batch of Kofta, some Koftas survived, other died like the former batch.My spirit was not crushed even after all this and I started preparing Gravy, it was one of the worst gravy fail of all time. I forgot that I dont have tomatoes!!!! Can you imagine an Indian curry without Tomatoes???My surviving Koftas were way too oily, I dont know whyyyy!!!!I had come this far so I went ahead and put those OILY Koftas in the Tomatoless Indian gravy.When I tasted it, I cried, not with happiness mind you, with the taste of utter failure!Never tried to make Koftas again!! Never!This is how it supposed to look like
------How did Led Zeppelin change music?
Led Zeppelin changed the course of music forever. Each member alongside being at the top of their respective crafts, continue to influence artists to this day.Robert Plant created the style of the classic rock lead man, with tight pants and a feminine yet somehow masculine style. This paved the way for others such as Axl Rose, Steven Tyler, and many more.Jimmy Page alongside Jimi Hendrix, is the most influential rock guitarist. His iconic riffs and and expressive solos remain as timeless classics, which continues to influence guitarists of our dayJohn Bonham is often considered the greatest drummer in rock and roll history. Without him setting the tone, masterfully combining elements of Jazz drumming with an aggressive rock style, it's hard to imagine Led Zeppelin reaching the heights it didJohn Paul Jones was the perfect piece to accompany the rest of the band. He was the most versatile of them all, playing bass, keyboard, mandolin and anything else the band required, filling in the gaps to perfection.Overall, this 4-man band combined to make the greatest rock band of all time, setting the standard to which any music in the genre is judged by. This is unfair to bands like AC/DC, Aerosmith, Guns and Roses, or even Greta Van Fleet today... They are all good in their own right but merely echo some parts of Zeppelin's brilliance. Yet, all these bands and many others demonstrate the far reaching influence Led Zeppelin has had on music
------What historical factors led to Malaysia being more prosperous and developed than Indonesia?
Most likely being colonised by the British, instead of the Dutch (in Indonesia.)Being smaller (land and population-wise) and easier to manage than Indonesia (Remember, Malaysia was simply Malaya before the latter teamed up with Singapore, Borneo Islands Sarawak and North Borneo - renamed Sabah sometime in 1963 - to form the federation of Malaysia in the same year.)Singapores port, and to a certain extent Malayas two main ports (in Penang island and Klang in the state of Selangor) generated much prosperity due to being ideally located along the Straits of Malacca, which is:
- One of the most important shipping lanes in the world.
- Busiest strait in the world.
- One of the world's most congested shipping choke points.
(All three points lifted off wikipedia, I humbly admit).West Malaysia is connected by land to the Asian continent, and this complements the sea trade & commerce routes, whereas Indonesia consists of islands and is therefore at a disadvantage, logistically-speaking.The abundance of tin ore in some parts of Malaya started a rapidly-flourishing, large-scale industry in the early 19th century. By 1883, Malaya had become the largest tin producer in the world. By the end of the 19th century, it was supplying about 55% of the world's tin.Rubber was introduced in Malaya in the late 19th century. By the 1930s, Malaya produced half of the worlds rubber. Before Malaya gained independence in 1957, rubber plantations helped transform Malaya into Britains richest colony. At one point, Malaysia was the worlds largest exporter of rubber.Just my loose, non-expert observation, obviously. Feel free to correct me or add anything. Thanks!
------What was the best episode of Star Trek (The Original Series), and why?
Amok Time.For these scenes:Kirk is ordered to Altair VI by Star Fleet, instead of taking Spock to Vulcan. Kirk states to Bones that theres no reason for the Enterprise to be there, that its not that vital, and hes going to Vulcan anyway. Bones tells him that it would mean his career. Kirk says I cant let Spock die, can I Bones? And he will if I go to Altair. I owe him my life a dozen times over. Isn't that worth a career? Hes my friend!Spock, Bones and Kirk are in the turbolift, getting ready to be beamed down to Vulcan. He asks Kirk to beam down to the planets surface, to stand with him, and Kirk asks if it is permitted. Spock says, It is my right. By tradition, the male is accompanied by his closest friends. Kirk thanks him. Then as the doors open, Spock also says, I alsorequestMcCoyaccompany me. Bones, quietly surprised and touched, says with great dignity, I shall be honored, sir.
The overwhelming joy of seeing Kirk alive, exclaimingJIMM!!!I've always felt Amok Time reflected the essence of the best of Star Trek. Jim, willing to throw away the thing we has always wanted to be, a Star Fleet captain for his friend. Spock, stripping away the token animosity and revealing his respect and friendship to Bones, and Bones showing how honored he feels to be considered a friend of Spock.
Again, the best of Star Trek.
